You cannot "convert" a FileStream into anything, let alone a MemoryStream.

What you could do, perhaps what you want to do, is read the entire contents
of a FileStream into a MemoryStream, or expose the entire contents of a file
through a MemoryStream.

If you could take a step back and describe the problem you're trying to
solve, someone can help.
